OIL-BURNER.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed December 26, 1918. Serial No. 268,262.

This invention relates to burners for va porizing and burning crude oiland the general object of the invention is to provide a burner of thischaracter which is very simple in construction, and which is veryeifective.

A further object is to provide a construction of this character in whichthe oil passing to the discharge nozzle of the burner is sub-divided andpasses through a plurality of heating pipes prior to its ejection fromthe burner so that the oil is vaporized before it is mixed with thesteam and ejected.

A further object is to provide very simple means whereby the oil pipesmay be cleaned 0r blown out.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure1 is a vertical longitudinal sectional view ofmy oil burner; and

Fig. 2 is a section on the line 2-2 of Fi .1.

l ieferring to these drawings, it will be seen that my improved oilburner comprises a steam chamber 10 which is illustrated as cylindricalin form and which is preferably formed of a main section and a head 11bolted, riveted or otherwise attached to the main section. This mainsection is formed with a nozzle 12 and into the steam chamber or chestextends the steam pipe 13 connected to a source of steam under pressure.

Extending through the head 11 opposite the nozzle 12 is an oil supplypipe 14 and dis posed in the nozzle 12 is an oil discharge nozzle 15which is on a line with the pipe 14. Connected tothe inner ends of thepipe 14 and the nozzle 15 are the crosses. Connecting the arms of thecrosses 16 are the pipes 17. It will thus be seen that the oil fed tothe burner after it enters the steam chamber 10 is divided into aplurality of channels and passes through the relatively small pipes 17so that all of the oil is thoroughly heated and, as a consequence. vaporized before it is discharged from the oil nozzle 15.

In order to provide means for cleaning the oil pipes 14, 15, 16 and 17 Iprovide a steam pipe 18 leading from the steam supply pipe 13 andentering the pipe 14. The main steam supply pipe 18 is provided with avalve 19 between the steam chamber and the junction of the pipe 18 andthis pipe 18 is provided'with a valve 20 and also with a valve 21adjacent the oil pipe 14. This oil pipe is also provided with a valve 22for controlling the flow of oilto the pipes 17 and the bottom of thechamber 10 has a drainage opening controlled by a cook 23 for removingwater from the chamber.

In the operation of this device the valves 20 and 21 are closed and thevalve 19 opened and the valve 32 opened. Oil therefore passes into thepipes 17 while steam passes into the interior of the chamber and thissteam is under relatively high pressure and its heat vaporizes the oilin the pipes 17. The steam discharges through the nozzle 12 and in doingso sucks out the vaporized oil through the oil nozzle 15 and ejects astream of steam and vaporized oil from the nozzle 12 into the furnacewith which the burner is used. If it be desired to clean the burner thevalves 19 and 22 are closed and the valves 20 and 21 are opened. Thispermits steam to pass through the pipe 18 and into and through the pipes14, 17 and 15 and blowing out all foreign matter within these pipes.

Inasmuch as the oil is rality of streams while passing through the steamchamber, it will be thoroughly heated so that the final combustion isperfect. Before leaving the burner the oil is thoroughly mixed with thedischarging steam jet and leaves the burner in the form of a fine vaporwhich is ignited near the nozzle and which burns with a white flame.This burning jet in practice has been found to extend far back into thefurnace and even up into the flues.

This burner is particularly valuable where crude oil is bein used, butis also capable of being used with any form of oil. The burner may bemade of various sizes but the nozzle of the burner is to have a depthequal to the thickness of the furnace wall.

I claim:

1. An oil burner of the character described including a steam chamberadapted divided into a pluto be connected to a source of steam underpressure and having a discharge nozzle, and an oil pipe entering thesteam chamber and connecting with a plurality of relatively small pipesextending longitudinally through the steam chamber, and a single nozzlepassing into the steam chamber nozzle and with which said plurality ofpipes are connected.

2. An oil burner comprising a steam chamber having a steam supply pipeadapted to be connected toa source of steam under pressure, the steamchamber having a nozzle at one end, an oil supply pipe entering the rearend of the steamchamber and connected to a plurality of radiating pipes,longitudinally extending pipes connecting to the radiating pipes andextending longitudinally of the steam chamber, an oil nozzle shorterthan and extending into the discharge nozzle ol the chamber andconnected to a plurality of radiating pipes at its inner end, to whichradiating pipes the longitudinal pipes are connected, and a valvecontrolling the pres sure of steam Within the chamber.

3. A burner of the character described including a steam chamber formedin two detachable sections and provided With a nozzle, a steam pipeentering the steam chamber, an oil supply pipe entering the rear end ofthe chamber opposite the nozzle, an oil delivery nozzle extendingpartially into the steam nozzle, a plurality of pipes connecting the oilnozzle with the oil supply pipe, a branch pipe extending from the steampipe to the oil supply pipe and having valves adjacent the steam and oilsupply pipes, and a drainage cock in the chamber.
